Question

What is the velocity of reaction?? what is rate of reaction ? what is instantaneous rate of reaction ???

Answer 1

The rate of reaction is the measurement of chemical activity of a certain reaction.

Explanation:

Due to my lack of knowledge, I have never came before the term of "velocity of reaction". However, I believe it shares the same definition as rate of reaction. Rate of reaction can be understood as the rate of change of the materials, such as the rate of depletion of the reactants or the rate of production of products.

Instantaneous rate of reaction is the rate of reaction at a specific time. For example, if a question is asked "what is the rate of reaction (or instantaneous rate of reaction) at 1 min?", then we can obtain the answer by plugging in `t=1min` into the rate equation of the reaction.
